70 Hudson Yards is a new high rise building north of Hudson Yards proper. As part of the new phase, 70 is intended to be the first tower in New York City to be considered a zero-carbon emission building. The building folds and shifts subtly throughout the building, providing views and outdoor spaces for the office tenants. The stone façade acts similarly as the building, shifting light and shadow throughout the form. On the lower floors of the building, the façade is held off three feet from the glassy exterior wall on a metal chassis, eroding the mass of the building as it lands on the ground. A glassy storefront meets the ground at the lobby entrance, inviting users to enter the ground and mezzanine amenity floors which will be filled with cafe and retail uses.
